Well if that is the case, then an MCAT score of 30 would correlate better w/ a USMLE score of 230 since a 30 on the MCAT is generally around the 75th percentile.... However, it is certainly not easy to relate how one performs on the MCAT with their aptitude for the USMLE. For one thing, the ppl taking Step 1 had an average MCAT score of 29-30 (they got into med school after all, didn't they
). So on one hand it would be logical to say that an average MCAT score for med school matriculants would correlate with an average USMLE score. But as far as percentiles go, it's a different story. A significant proportion of MCAT takers will never step foot into medical school, whereas the great majority of those who sit for the boards will become physicians. It is also important to consider the emphasis that different types of med students place on the exam. Many ppl are content to receive just any passing score because their interests lie in fields of medicine that may not typically place much emphasis/value on high board scores. For highly competitive fields, however, the Step 1 score is quite often the very first thing they look at when assessing applicants.
